Exch2k3 migration question

Hello,

We have an Exchange 2003 Org in a single domain/forest.  Recently, we bought
a small company with about 200 users.  They too have their own AD/Forest and
Exch2k3 Org (I'll call this the source).  The long term plan in 2008 is to
consolidate all resources (users, desktops, servers, etc) from the source to
our forest.  These users have already been set up with user accounts in our
AD for other reasons.

All of a sudden, because thier Exch2k3 server hardware is failing, they want
to migrate their mailboxes off the server in thier Org and onto the server
in our Org.  They don't have a problem haven't to always put in credentials
when they open up Outlook.  So, since they already have user accounts in the
target AD, can we simply "mail enable" them then user ExMerge to pull down
the mailboxes to .pst files and then import them into the target mailbox?
Or, is there an easier way?

Also, we'll need to migrate their schedule free/busy information from the
source to the target.  Basically, for now they want to sit down at the desk,
log into the desktop with the source account/password and when they launch
Outlook, have their mailbox on the target server and put in credentials.

Is this technically possible?  I know it doesn't sound like best practice,
but it's short term and a small amount of users.

Thanks

You can do that but you're going to break lots of things.  Seriously, you
should consider using a third-party tool like Quest's migration suite.

Thanks Ed.  Could you give me a few examples of the risks we'll be taking?
I'm pretty sure Quest has a minimum seat purchase and again, we're very
small so we don't feel it warrants the investment as it's quite pricey.

Personally, the only thing I can see running into an issue is the public
folders/free busy.  Merging 200 mailboxes down to a pst (or even using the
native ms exch migration tool for that matter) should be pretty straight
forward.

Any further information would be appreciated.

Thanks

There are issues of message replyability, users' Contacts and Personal
Address Book entries, manager-delegate relationships, and more.  If you're
small, you might find these issues to be manageable.
